I'm afraid it is final for me. Maybe someone else will step up.

I'm not willing to work under some elaborate rule set what I may and may
not do with the AST. It is way too easy to make a mistake, and a few
years ago I've learned the hard way that there's no such thing as an
"honest mistake" when it comes to software's freedom. Also, what happens
if someone else takes my code and simply rewrites it to dump everything?
It would be trivial, since the real work is walking the AST and
extracting its information. The only solution for defending against this
is to restrict access to the AST in GCC's plugin interface, rendering my
plugin unusable. Also, I seem to be unable to discuss with Richard
without him calling out my behavior, so I'm clearly not the right person
for this job.
